1.4301 Stainless Steel Bright Annealed Tube

If you are looking for high-precision stainless steel tubes with excellent surface quality and clean inner walls, we offer 1.4301 bright annealed stainless steel tubes, specifically designed for applications requiring both aesthetic appearance and reliable performance.

We supply high-quality 1.4301 bright annealed tubes, processed with bright annealing (BA) in a controlled hydrogen atmosphere. After bright annealing, the surface roughness is Ra≤0.4μm, resulting in a smooth surface and clean, oxide-free inner walls with strict dimensional tolerances. This helps reduce friction, prevent media contamination, and improve fluid transfer efficiency. Furthermore, 1.4301 stainless steel welded tubes are non-magnetic in the annealed state, resistant to atmospheric and weak corrosive media, and exhibit excellent welding and cold bending properties, requiring no heat treatment after welding. They are widely used in sanitary and general industrial applications such as food and beverage, pharmaceuticals, water purification, precision instruments, and building water supply and drainage systems.

1.4301 stainless steel polished tubes undergo 100% spectral composition testing before leaving the factory, and each finished product is subjected to a hydrostatic pressure test, conforming to EN 10216-5/DIN standards. Each batch is accompanied by an EN 10204 3.1 material certificate, and the entire process is controlled under ISO9001/TPED certification. The products are exported year-round to over 40 countries in Europe, America, Southeast Asia, and the Middle East, with an average monthly export volume exceeding 900 tons. Minimum order quantity is 500kg, and stock items are shipped within 3-7 days after customs clearance.
